The coupling of sulfonimidoyl fluorides and alkynes using sulfur(VI) fluoride exchange (SuFEx) reactions has not been available because of the intrinsic reactivity of the π component. Now, a divergent SuFEx process between sulfonimidoyl fluorides and alkynes to produce vinylic or acetylenic sulfoximines is reported. Mechanistic studies reveal the origins of the vinylic sulfoximines, and several synthetic transformations of the products demonstrate the utility of the process.
